Fleece Performance 11-16 GM 2500/3500 Duramax LML CP3 Conversion Kit w/HD CP3

Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms, resulting in costly repairs for owners when a CP4 fails. Our CP3 conversion kit lets you easily adapt a CP3 to your 2011-2016 Duramax.

In conjunction with the piezoelectric injectors, a CP3K conversion is capable of supporting 600 and up rwhp and a PowerFlo 750 conversion is capable of supporting nearly 850 and up rwhp.
